- Chemistry C2.
- Subtances.
- Immiscible.
- substances that will not mix together but will form distinct layers.
- Immiscible.
- Subtances.
- ie) water and oil, water is separated from oil using a funnel.As soon as all the water runs out of the funnel, tap closed

- Subtances.
- Liquids are mixed and stay together
- Subtances.
- Liquids are mixed and stay together
- separated using distillation or fractional distillation.
- Rates of Reaction.
- Chemistry C2.
- Larger surface area-more particles exposed and available for collision.
- high conc- particles are closer together,more collisons
- Chemistry C2.
- Endo+Exo.
- Exo- rise in temp, heat is transferred to surroundings-combustion. Energy released when bonds are made.
- Endo+Exo.
- Endo+Exo.
- Endo-fall in temp,heat transferred in FROM surroundings-ie-dissolving ammonium nitrate crystals in water. Energy must be supplied to make bonds.
